The standard was approved without further revision on Jan. If the outside diameter of the pipe is larger than the nominal diameter, the dimensions can be calculated from the appropriate formulas. In this procedure, the pipe end is miter cut, and then the bell is expanded square with the face of the miter cut see Figure 2B.

Minimum dimensions for 90″ wyes are stated in Table 1. With the development of the Bessemer process in and the open hearth process in ,steel, the strongest and most versatile refinement of iron, became available for water pipe. The AWWA standards usually contain options that must be evaluated by the user of the standard. In special circumstances where a standard nozzle and 90″ elbow cannot be used, a tangent nozzle may be used. In small diameters 4-in.

Add additional length to these dimensions when necessary for flanged, mechanical couplings, or bell and spigot joints, or as needed to meet other design conditions. Other angles from 90″to 30″ may be used.

The length of reducers L, is calcu- lated by the following formula. AWWA standards are intended to represent a consensus of the water supply industry that. The use of A W A standards is entirely voluntary. AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally contained in specifications.

Deflection angles up to 5″ can be taken in welded butt joints using miter end cuts of one or both pipe ends, provided that the difference in circumference of the true circle and the ellipse formed by the miter end cut does not result in a joint fit-up that would exceed the allowable plate edge offset see Figure 2A.


The stipulations of this standard apply when this document has been referenced and then only t o dimensions for fabricated steel water pipe fittings. The fitting dimensions shown in Figures 1, 2, 3, 4, and 6 and in Table 1 are the minimum dimensions for fittings with plain ends.

Producers of goods made in conformity with a n American National Standard are encouraged to state on their own responsibility in advertising and promotional materials or on tags or labels that the aww are produced in conformity with particular American National Standards.

ANSI procedures require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication.

Submittal of shop detail and assembly drawings. The optimum radius for a fabricated elbow based on these considerations is 2. This method of fabrication continued with improvements into the s.

If necessary to enable the valve operator to clear the outside diameter of the run pipe, a flanged spool should be used to extend the connection as required. These revisions include the following: For angle 0 less than c280, use 30″ lateral wye plus an elbow. Miter welds greater than Refer to Figure lD, Case 1 [equal diameters]. For an angle 8 less than 30″, use c20 lateral wye plus an elbow.

Qf is a factor to be used in formulas to calculate design dimensions. The aforementioned guidelines for dimensioning fabricated steel pipe c28 represent good practice for water transmission mains.

Deletion of Table 5.


The major revision was to clarify that the standard is a dimensional guide only and that design of fittings should be in accordance with applicable sections of AWWA Manual M Warren, Tetra Tech Inc. Dimensions A and B can be calculated using the following formulas: This standard is intended to wawa as a dimensional guide only.


Tangent dimensions provided in Table 1 or calculated by the formulas are minimum dimensions for fittings with plain ends or beveled ends for field welding. Reinforcement of fittings, which may include increased wall thickness, collars, wrapper plates, or crotch plates, is not covered in this standard.

Qwwa following guidelines for dimensioning fabriReferring to Figure 2, 1. Wise, Canus Industries Inc.

This radius is recommended as a standard for water transmission lines where space requirements permit. Revisions to the text were approved on June 21, ,and incorporated in the sixth and later printings.


This represents good practice that will f208 in maintaining the roundness of pipe ends. In their latest editions, these documents form a part of this standard to the extent specified within this standard.

Addendum 2, was approved on June 4, It was approved as a “tentative” standard on July 14, The addendum added a note of caution to Tables 2A through 2D concerning hoop tension concentration awwz elbows was with a radius of less than 2.
